Step-by-step explanation:
Cows have
legs and 3 toes on each leg, if we want to find the number of toes of ONE cow we have to multiply the legs by the toes giving the following:
![3(x+3) \quad (1)](https://tex.z-dn.net/?f=3%28x%2B3%29%20%5Cquad%20%281%29)
But we have two cows so (1) we have to multiply it by 2 giving a total of:
![2(3(x+3))\\6(x+3)\\6x+18 \quad (2)](https://tex.z-dn.net/?f=2%283%28x%2B3%29%29%5C%5C6%28x%2B3%29%5C%5C6x%2B18%20%5Cquad%20%282%29)
By the other hand chickens have
legs and 7 toes on each leg, if we want to find the number of toes we have to multiply the legs by the toes giving the following:
![7(2x-4)\\14x-28 \quad (3)](https://tex.z-dn.net/?f=7%282x-4%29%5C%5C14x-28%20%5Cquad%20%283%29)
To find the total amount of toes we have to add (2) and (3)
![(6x+18)+(14x-28)\\20x-10](https://tex.z-dn.net/?f=%286x%2B18%29%2B%2814x-28%29%5C%5C20x-10)
